TO ALL WHOM IT MAY CGNCERN:

Be it known that Ig CLARK R. HEWETT, of Waupun, in the connty of Dodge, and State of Wisconsin, have invented a new and improved Combined Fodder-Cutter and Corn-Sheller; and I vdo hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming 'a part of this specification, in which- Figure 1 is a top view of my combined machine, a part of the cover being removed.

Figure 2 is a side view of the same, the cutter-box being removed, and portions of the panelling being broken away.

Figure 3 is a vertical section of the same, taken through the line x x, g. 2, the cutter-box being in place.

Figure 4 is a vertical section of the same, taken through the line y y, g- 1- Similar letters of reference indicate like parts. i

My invention has for its object to furnish a machine by means of which corn may be shelled o1' fodder cut, as may be desired, with equal facility; and itconsists, first, ofthe balance-wheel, and the shafts and bevel-gear wheels by which motion is communicated to said balance-wheel, in combination with each other and with the frame ofthe machine; second, the combination of cutter-knives and Sheller-teeth with the balance-wheel of a combined fodder-cutter and corn-Sheller; third, the combination of the rubber springs with the knives and balance-wheel; fourth, the feed-rollers, in combination with each other, with the. driving-shaft, and with the frame of the machine; the whole being constructed and arranged as hereinafter more fully described.

A is the foundation-frame or feet ofthe machine; B, C, and D are the uprights or frame of the machine; E, F, and Gr is the horizontal frame which supports the casings ofthe machine; H and I are cross-timbers connecting the up'ights B and C; J is the driving-shaft. This shaft revolves in bearings attached to the uprights C and D; and to its outer end is attached the crank K, by which motion is communicated to themaehine. To the inner end of the shaft J is attached a bevel-gear wheel, L, which meshes into a bevel-gear wheel, M, attached to the shaft N. This shaft revolves in bearings attached to the uprights D and C, and to it is attached the balance-wheel O. Io the side of the wheel O are attached two or more knives, P, so arranged that the end of the knives Yfarthest from the centre f the wheel 0 shall first come in contactwith the material tobe cut. The knives? are attached to the wheel by screws passing through slots in the vsaid knives, by which means'the position of the knives may be adjusted as required. Between the knives P and the side of the wheel O are placed rubber springs R, which 'keepthe knives P pressed out against the stationary knife attached to the edge ofthe mouth-piece of the'cutter-box. The otherside of the xbalance-wheel O is covered with lprojecting castiron teeth S, asshown in iig. I. Its central part is also provided with radial flanges T, equalling, or a little exceeding, the teeth in height; the object of which will be hereinafter described. U is a wooden bar, hinged at its upper endv to the top of the upright, B, as shown in the drawings. To its under side is attacheda spring, V, resting against the innerside of the casing W, as shown in iig. 3. i The tendency of this spring is to force the block or bar U inward towards the balance-wheel O. 'lo'the inner side of the bar U isfirmly attached a grooved or half round metallic plate, X, along the groove of which the ear of corn passes into the machine. A1 is a plate, immevably attached to the casing Wby a Iiange, as shown in Iig. 4. The projecting edge of this plate should extend so far towards the balance-wheel O as to prevent the ear of corn being revolved out of the groove in the plate X by the action of the teeth S, and its projecting edge may be serrated, if desired, so as to allow the kernels of corn to pass through it. B1 is a metallic plate, made in the form represented in iig. 4, the face of which is toothed, as shown. It has also a half round groove, C, along its upper edge, said groove lead-A ing to an opening through the edge. casing, as shown. The ear of corn enters through an opening in the top of the machine,` as seen in tig. 1; thence it.passes down along the groove in the plate X, being all the time acted upon by the teeth S; thence it passes down through theigrooved neck part D of the plate Bl. When it reaches the body or chamber of said plate Bl, it is revolved by the action of the teeth S andangcs T across the toothed face of said plate into the grooveC, and thence to the outside of the machine, thecorn` having been entirely removed during its passage. The corn escapes at the bottoni ofthe machine through the spout E. The plate Bl is firmly attached to the wooden bar F', and is held forward towards the balance-wheel O bythe spring` G', which is attached to the bar F', and presses against the face of the casing W, as shown in fig. 1. The end of the bar F is attached `to the casing W by a hingqH, as shown in iig. 4. The machine should be encased, as shown, to prevent the corn from flying about. -To the projecting end of the shaft J` is attached asmall cogwheel, I,whieh meshes into the cog-wheel J"attaehed to the shaft K. This shaftrevolves in bearings attached to the upright lj), and vhas on -its other end a small cog-wheel, Lf, which meshes' into a cog-wheel,-M securely attached to the end of the feed-roller N. The cog-wheel Of is also attached, in connection with the'cog M., to the end of 'the Said roller N, and it meshes into the cog-:Wheel P attached to the shaft R of the upper feedrollel` S. The roller N revolves freely uponthe shaft J, but the roller S is attached to and revolves with its shaft, R. The shaft R revolves in slotted bearings` attached to thc uprights C and D, and is held down to its lace and enabled to adjust the s ace between the rollers to the amount ot material assinfr throu h thc cutter- P P P e g bei, by hooks or links T', the lower ends of v'which are `connected with the spring U', as shown, in fig. 2. V is the mouthpiece of the cutter-box. This mouth-piece is east solid, 'with a downwardly-projeating apron, the lower edge of which is attached to the horizontal frame E, as shown in' tig. 3. And to its upper` edge is attached the stationary knife W, by screws passing throughyslots in said knifebs as .to make it adjustable. The cutter-bci: X lis made in the usual manner and form, and-is attached.- to the frame of the machine by means of a metallic strap, A2, passing a'roundlthe end of the said cutter-box, and hooking over catehesattached to the upright C and D. The cutter-box maybe still further suppoted by aired, B2, hookinginto eyes att-ached to the upright C and the edgeof the cutter-box X, as shown iu iig. 8.

I claim as new, and desire to secure by Letters Patent- .1. The combination of the 'shafts J N, hevehgear wheels L M, cutter-knives P, and. shellerteeth S, with i the balance-Wheel O of a combined fodder-cutter and corn-Sheller, substantially as described, and for the pui'- poses set forth. l

2. The combination of the rubber springs R with the knives P and balance-wheel O, substantially as described, and forV the purpose set forth.
